Problems solved by technology
[0003] The copper matte produced by the smelting device needs to be transported by chute, crane, or sent to the blowing furnace after water quenching and solidification, which has the problems of long process, large investment, and high energy consumption. Moreover, due to the discontinuous increase in discharge operations, SO 2 spill pollution

Abstract
The invention discloses an integrated continuous copper smelting device and method.The device comprises a smelting area and a blowing area, the smelting area and the blowing area are separated through a partition wall, a hole is formed in the lower portion of the partition wall, a smelting slag chamber is arranged in the smelting area, a blowing slag chamber is arranged in the blowing area, and three layers of melts are arranged in the smelting area from top to bottom; a smelting area slag layer, a smelting area copper matte layer and a crude copper layer are arranged in sequence; three layers of melts are arranged in the blowing area from top to bottom, and are a blowing area slag layer, a blowing area copper matte layer and a crude copper layer in sequence; the smelting area is provided with a first air blowing-in opening and a second air blowing-in opening, primary oxygen-enriched air is blown into a slag layer of the smelting area through the first air blowing-in opening, and secondary oxygen-enriched air or normal-oxygen air is blown into an upper gas-phase space of the smelting area through the second air blowing-in opening; the blowing area is provided with a top-blowing spray gun, and oxygen-enriched air is downwards sprayed into melt in the blowing area from the top-blowing spray gun. The process can be shortened, the investment is reduced, the energy consumption is saved, and SO2 leakage pollution is avoided.
Description
technical field [0001] The invention relates to the technical field of smelting, in particular to an integrated continuous copper smelting device and method. Background technique [0002] At present, copper pyrometallurgy is divided into two stages: smelting and blowing, which are completed in two independent devices. The smelting device produces copper matte, which is then sent to the blowing device for blowing to produce blister copper. Melting devices include electric furnaces, reverberatory furnaces, flash furnaces, side-blown furnaces, Austrian furnaces, bottom-blown furnaces, etc., blowing devices include converters, flash furnaces, Austrian furnaces, top-blown furnaces, bottom-blown furnaces, etc. [0003] The copper matte produced by the smelting device needs to be transported by chute, crane, or sent to the blowing furnace after water quenching and solidification, which has the problems of long process, large investment, and high energy consumption, and the discont...
